CombiMaster 230V Series
– User and Installation Manual
Use M8 cable lugs on the ends of the wires. These lugs should be crimped with a proper crimping tool.
Recommended wire colors (refer to local rules):
Run the cables next to each other to limit the electromagnetic field around the
cables. The negative cable should be connected directly to the negative post of the
battery bank or the ground side of a current shunt. Do not use the chassis frame as
the negative conductor. Tighten securely.
The positive cable must be fused and connected to the positive post of the battery bank. Use a fuse that matches the applied
wire size. The fuse with fuse-holder is available from your local Mastervolt distributor.

AC wiring
WARNING!
The ground wire offers protection only if the case of the CombiMaster is connected to the safety ground. Connect
the ground terminal (PE / GND) to the hull or the chassis.
CAUTION!
According to local regulations an RCD/Breaker (also known as GFCI) must be placed in the AC input
and
output
circuit of the CombiMaster.
For a safe installation the correct wire cross section must be applied. Don’t use a cross section that is smaller than indicated.
Recommended cross section for the AC wiring:
AC Current Minimum cross section
0-20 A
2.5 mm²
20-32 A
4 mm²

AC Safety grounding
WARNING!
For safety reasons Residual Current Devices (RCDs), also known as Breakers or Ground Fault Circuit Interrupters
(GFCIs), of 30mA must be integrated in the AC input and AC output of the CombiMaster. Refer to locally applicable
regulations regarding grounding of autonomous power systems.
If an RCD or GFCI is used, place the grounding system jumper (located on
the left side of the CombiMaster) on N and PE.
Default setting
Combined PEN
4.5.4
Network wiring (CZone/MasterBus)
The CombiMaster can be connected to a CZone or MasterBus network. For CZone, use an RJ45 Drop cable CZone/MB. For
MasterBus, use a MasterBus cable and daisy chain the CombiMaster to the other devices. Both networks need a terminating
device on both ends of the network. Do not make ring networks. For more details on networks, please contact your Mastervolt
supplier.
